I want to model the moving mass (not vehicle) in sap 2000, Can anyone help me?
Hello Houman,
A moving load can be modeled in SAP2000 as follows:
1. Define a load case for each load location and name each load case according to the loading sequence.
2. For each load case apply a point load in the corresponding location.
3. Define a single time-history function, which will represent the loading sequence.
4. Define a time-history analysis case.
5. Add each load case to the Loads Applied section and specify the impulse function, scale factor, and arrival time.

Hi Dr. Vitaiy
Thank you for your answer
My keyword to search in this website was "moving mass" and I can not any data.
But you suggest good link. This link is about moving LOAD but I am follow moving MASS.
Can help me more?
Best Regards
Houman,
In SAP2000, mass sources can be defined from loads. So, if you define the mass source from the moving load, the moving load will become a moving mass. Will this work for you?

Thanks for your answer. Your answer is true. modeling the vehicle is three method and there are numerical methods for solution. I checked it with numerical methods.
Thank you
